HAY-RACK LOADER.

SPECIFICATION forming part of Letters Patent No. 609,148, dated August16, 1898.

. Application filed April 7, 1898. Serial No. 676,757. (No model.)

To all whom it may concern:

Be it known that I, SETH KELLUM, a citizen of the United States,residing at Milford, in Dickinson county, Iowa, have invented a new anduseful Automatic Machine for Lifting a Hay-Rack OE and On a Wagon, ofwhich the following is a specification.

My invention relates to a machine for taking a hay-rack 01f a wagon andputting it on again without the usual lifting. I attain these objects bythe mechanism illustrated in the accompanying drawings.

Figure l is a side View of the entire machine with hay-rack, representedby dottedlines, resting upon it. Fig. 2 shows the machine when thehay-rack is off. Fig. 3 shows one of two similar blocks fastened one toeach of A A in Fig. 5 to support the front ends of the tracks D D whenthe machine is in the position shown in Fig. 1. Fig. 4 shows one of twosimilar blocks fastened one to each of the posts O O in Fig. 5 tosupport the rear ends of the tracks D D when the front ends of thetracks are tilted up, as shown in Fig. 2. Fig. 5 is a top view of themachine. Fig. 6 shows one of two similar pivots upon which the tracks DD tilt, fastened one to each of the posts D D, shown in Fig. 5. Fig. 7shows how each of the flanged wheels H H H H,

which support the weight of the rack on the tracks D D, is fastened tothe cross-pieces ofthe rack.

The machine consists, essentially, of two timbers four by four inchesand about four feet longer than the hay rack, as shown in D D, Figs. 1,2, and 5, hung on pivots F F and supported at the front ends by blocks NN, bolted to the posts A A, as shown in Fig. 3, when loaded withhay-rack, as shown, and supported at the rear ends by blocks L L, boltedto the posts O O, as shown in Fig. 4, when the tracks are in theposition shown in Fig. 2. The pivots F F, on which the centers of thetracks D D tilt, are supported by two posts, the ends of which are shownat B B, Fig. 5, and one of which is shown at B I in Figs. 1 and 2. Thetwo posts B B, on

D D between the posts and the rack, as shown in Fig. 5. i r

The posts AA, the ends of which are shown in Fig. 5 and one of which isshown in Figs. 1 and 2, are set in the ground at the front end of themachine and placed the same distance apart as B B. The posts 0 O, theends of which are shown in Fig. 5 and one of which is shown in Figs. 1and 2, are placed near the rear end of the machine and the same distanceapart as the posts B B. Four small flanged wheels H H H H, as shown inFig. 5, are fastened to the ends of the second and fourth cross-piecesfrom the front end of the rack and carry the rack on the tracks D D.These wheels are fastened to the ends. of the cross-pieces of the rackby iron straps. bolted to the said cross-pieces, as shown in Fig. 7.

The pivots F F, fastened to the posts B' B, and the blocks N N, fastenedto the posts A A, must be of such height that when the tracks D D arehorizontal the rack resting upon them will be lifted clear of the wagon.The blocks L L, fastened to the posts 0 0, must be of such height thatwhen the rear ends of the tracks D D rest upon them the front flangedwheels H II will just pass upon.

wheels of the wagon will just pass between them when taking off orputting on the rack. Short pieces of timbers J J J J the same size as II diverge fromthe ends of the wheelguards I I and are joined to them toform approaches to the wheel-guards. I

The letters E E E E inFig. 5 refer to longitudinal braces to hold theposts BB in position, two of which braces areshown in Figs. 1 and 2Short cross-braces M M M M M M are placed one to each of the posts A A BB O O, as shown in Fig. 5.

To take the hay rack off the wagon, the wagon, with the rack on, isdrawn between the tracks from the rear end of the machine, thewheel-guards I I keeping the wagon from runing to one side or the otherwhen the front flanged wheels H H, fastened to the crosspieces of therack, travel up the incline of the tracks D D as the wagon is drawnforward, raising the front end of the rack off the wagon and continuingup the incline until the front flanged wheels, which carry abouttwothirds of the weight of the rack, reach a point in front of thepivots F F, where a greater portion of the weight of the rack will restupon the front ends of the tracksD D, when D D will balance down at thefront ends and I rest upon the blocks N N, fastened to the backed underthe rack, the horses pushing the rack back until a greater part of theweight of the rack falls behind the pivots F F, when the rear ends ofthe tracks D D will balance down and rest on the blocks L L, fastened tothe posts 0 O, as shown in Fig. 4.

The rack starts to roll down the incline of the tracks D D, but is keptfrom running too far back by the blocks K K,fastened to the sides of thebed-pieces of the rackd d, as shown in Fig. 5, which catch on thestandards of the hind bolster of the wagon. The wagon is backed up,letting the front end of the rack down to its place in the bolster asthe front flanged wheels H H roll down the inclinetracks D D. When therack is on the wagon, the wagon is backed away from the machine.

What I claim as my invention, and desire to'secure by Letters Patent,is-

A device for lifting a hay-rack off and on a wagon comprisingsupporting-frames, beams centrally pivoted upon said frames and adapt-.
